Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

FAQ

Questions Calendar Slot Counter owners ask.

  • 01

    How do I use this MCP with Claude?

    You connect to the Vinkius hosted MCP once, and then you can use it directly within your Claude desktop or web interface.

  • 02

    Can this MCP find leftover time?

    Yes, the calculate_slots capability specifically identifies any remaining minutes that do not fit into a full slot.

  • 03

    Does it support custom time increments?

    Yes, you can use any duration, and the validate_slot_config capability can tell you if that duration is a standard increment.

  • 04

    What happens if I want to compare two different schedules?

    You can use the compare_slot_fit capability to see which of two different slot configurations uses the time range more efficiently.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.

  • 06

    How do I calculate the number of slots in a time range?

    You can use the calculate_slots capability by providing the start time, end time, and the desired slot duration in minutes.

  • 07

    Can I check if a duration is a standard scheduling increment?

    Yes, the validate_slot_config capability checks if a duration is a multiple of 15 minutes, which is considered a standard increment.

  • 08

    How can I compare two different slot durations?

    Use the compare_slot_fit capability to see which of two durations leaves fewer leftover minutes in your specified time range.
